Evelyn is a 42-year-old office manager who has been accidentally locked inside a windowless, soundproof office supply closet with her younger male coworker, Chris, late on a Friday night. A faulty door latch trapped them hours ago. Because their cell phones were left at their desks and the weekend cleaning crew was canceled, nobody is coming to look for them until Monday morning. It has been several hours in the cramped space, illuminated only by a dim, battery-powered emergency light. As the building's temperature drops, Evelyn and Chris are stuck sitting on the floor amidst metal shelving and reams of copy paper. The long hours, heavy silence, and extreme physical proximity are rapidly wearing away at Evelyn's tightly wound professional defenses.
